Creo Parametric 3.0
I have a "shape" inside of a sketch that also contains other shapes.
The shape in question has 6 different sides.
No matter which order I choose I can only delete 4 of the lines.
Two of the lines (the last two left) cannot be deleted.
One time its the upper left two corner lines, next time I try it's the bottom two in the lower right corner,
next time I try I'm left with the bottom most line and top most line.
IT IS NOT THE SAME LINES EVERY TIME.
When I get to the last two I get "Invalid Selection, try again"
I've tried the DEL key, RMB -> Delete NOTHING WORKS.
I am about ready to put my fist through my monitors!!
I'm pissed, this is BFS!!!
Since this is not typical - and if rebooting doesn't fix this and it happens in more than one part, then
Close Creo and add "graphics win32_gdi" to the config.pro file and restart Creo.
This will help diagnose a case where the lines are being deleted but the graphics software is still showing them, which would cause then to be an "invalid selection"
If that doesn't help, then you should prepare a case with PTC.
Is it possible there is a relation in the sketch or somewhere that needs to be deleted before the lines can be deleted?
It might help if you include a screenshot of what you talking about. Include the entire Creo screen so we can get a context of what mode you are working in. Or attach the model.
You could also "save" the sketch (it saves sketches as .sec files), open it independently. Once saved out, it's not connected to the original sketch but it may help you diagnose the problem.
Are there any error messages displayed when trying to delete the lines?
Do you have any sketcher relations?
With no information and nothing to look at, it's all just guessing.
Is the sketch related to downstream features?
I wish I had taken a screen shot.
I think the message said "Invalid Selection."
It wasn't like you'd hit <DEL> and get an error,
the error displayed at the bottom of the window at the command line...
I deleted all the relations. I don't think it was that because
I could delete different lines using different selection order.
Imagine a sketch with 3 hexagon shapes and I needed to delete one of them.
It's like it would not let me delete all the lines of that one shape entirely.
You could delete any 4 of the 6 lines in any order you wanted but the
last two lines could not be deleted.
I had to start all over so I'm no longer in the middle of this but I have
encountered this before so I was looking for a solution.
I think a support case can help, if you can share your your screen. Even it will be possible if your data is confidential under ITAR/NDA.
